.
Check that the pump is operating correctly;
Measure that appliance performance; it must corre
-
spond to that declared in the technical features.
Check air is purged from water heater (see section 6.5)
If the pump does not operate, it must be replaced.
If the appliance is under-performing, the primary
heat exchanger might be dirty either on the exhaust
flue side or the domestic water side or both. Follow
instructions in section 8.4 and check again.
Loc 17
Software error inside the
command board
Replace the command and control board.
Loc 18
Software error inside the
command board
Replace the command and control board.
Loc 19
Software error inside the

Replace the command and control board.
Loc 20
Flame still present 10 sec.
after closing gas valve
Replace the gas valve or the command and control
board.
Loc 21
Flame present before
ignition
Replace the gas valve or the command and control
board.
Loc 22
Flame lost three times
Control: that the ionisation current is at a value over 4
(follow the procedure in section 8.13)
Control: that the exhaust flue system is not being
affected by high gusts of wind or nearby mechanically
operated fans
If the ionisation current is not over 4, the CO2 must be
checked (follow section 6.7) and restore the correct
value. Check the ionisation electrode and replace it if
necessary. Check the integrity of the ionisation current
electric circuit cables.
If a horizontal exhaust flue terminal is exposed to
unusually high wind conditions or nearby mechanically
operated fans then a suitable deflection shield or
protection should be considered or an alternative
location should be considered. The same approch
should be taken for a vertical exhaust flue and in
addiction, check that downdraughts are not being
encountered due to the proximity of higher roof profiles.

Check that the electrical resistance of the two sensors
match the graphics in section 8.14;
If one of the two or both sensors do not have correct
values, they must be replaced;

Hot water temperature is not stable Repeat calibration procedure (see section 6.8)
Check if pump is in speed 3
Water flow is present but the water
heater doesn’t work
Check if the water flow (parameter 1062) is higher
than the minimum water flow as stated on section 7.7.
